300+ wordpress migration on Fargate

My customer wanted to migrate 300+ wordpress hosted on EC2 farms on containers. I made an architecture with Terraform / ECS Fargate (on Spot and On-Demand) / ALB with auto-scaling / CloudFront / RDS / EFS / AWS Backup / CodePipeline The solution is fully resilient , available on multi AZ and cost have been optimized (Cloudfront agressive caching) Wordpress theme deployment is automatically done when a push to master is done on Bitbucket with the help of Bitbucket
